Path to Event-Driven Architecture (EDA)

As you can notice, the software architecture industry is moving toward ecosystems of microservices. Each microservice serves a specific business capability, and therefore manages related data elements. If we look at the entire set of connected systems under medium or large-size enterprises, it is natural to ask questions about data consistency across an organization.

CAP theorem suggests that we need to give up either real-time consistency or availability, as we cannot have both at the same time.
